Siseman, you forgot we had to wear ties.
Then the rules changed and you could remove ties outdoors but had to wear them indoors.
Then you could remove your jacket but had to roll your sleeves up.
We started to keep our sleeves down when jackets were removed. They then ordered us to roll our sleeves up but instituted a trial of sleeves worn down. This was at Akrotiri and the trial extended to just 3 people; the PA to the Stn Cdr, OC Ops Wing (Gp Capt Mike Beavis) and one other. It was deemed a success and we were all allowed sleeves up or down
Some years later on a particularly hot summer the staish at Waddo allowed the women (not WRAF) to forego tights. 'Advisor Airwomen' said this was not permitted and they had to wear tights again.
Remember also in the Cornish Riviera the groundcrew used to go in to KD.
